B.2. Version Control
You might want to consider some form of version control system in your development lifecycle or workflow, if you haven't already. Version control systems provide a way to store historical snapshots of code during development, and allow multiple developers to check files in and out of the repository, controlling the evolution of the codebase. Two of the most popular open-source version control systems in use today are CVS and Subversion.
CVS and Subversion are each version control systems that support the same basic features: historical records of file versions, and multiple developer support with check-in/check-out functionality. CVS has been around since 1989, and is the perennial favorite among many developers. Subversion is newer to the scene, first appearing late 2000, but is quickly gaining devotees because of its feature set, which extends beyond the "standard" functionality found in CVS. Features such as atomic commits, "safe" file renaming, file and directory copying, and WebDAV support are some of the reasons that many developers are going with Subversion these days. If you are looking for a robust feature set with good support both client- and server-side, Subversion is probably your best bet. If you're looking for stability, track record, and support built-in to many development tools, CVS is probably preferable—although more and more development packages are gaining Subversion support lately.
